Just bought it with the a/c inop. Gauges show around 25 psi so I figure it's just a little low. Connect my drum of freon with a heater and after about 10 minutes it only takes 7 oz. Gauges around 60 low 90 high at 80 degrees. Both lines warm. What should be my next step? It has 220,000 miles so I assume replace the compressor?
Recover the charge and recharge with proper amount. That way you can eliminate refrigerant charge as a problem. Most AC problems are low refrigerant problems. You could have a stuck control valve in the compressor. Easier to eliminate charge as a troubleshooting step.
Was able to add another 10oz with engine at 2,000 rpm and air got cold. Soon as it went to idle it was warm again. Seems like control valve issue.
